Jonah: You would be referring to the former Gary Hartpence? This isn’t his first comeback. Or his second. Here’s the article I wrote on him for NR in 2003:

Some people are afraid of heights. Others are scared of spiders. Gary Hart has a different phobia, according to a quote on his website: “My greatest fear is never having another opportunity to serve my country.”
Yes, the former Democratic senator from Colorado is thinking about running for president. Again. …
If September 11 hadn’t happened, Hart would be little more than a footnote in political history as the philanderer whose sudden downfall was a prerequisite to Bill Clinton’s political survival. But the terrorist strikes helped revive his career, lending him a veneer of respectability. In February, a profile in The New York Times Magazine declared that Hart’s national-security commission had “essentially predicted the terrorist attacks on Sept. 11.”
Hart’s commission does deserve some credit: It warned of terrorism at a time when more people should have cared. But it’s silly to say that Hart “essentially predicted” 9/11. “Americans will likely die on American soil, possibly in large numbers,” because of “international terrorism,” the commission warned. This would happen “over the next quarter century.”
That doesn’t exactly rate as a bold pronouncement. It’s rather cautious — even hedging. It also doesn’t square with something Hart wrote in his 1998 book The Minuteman: “Why do we have 1.5 million men and women under arms with no major threat to our security?” One reason, of course, is to have the strength to knock off the Taliban — or any other regime that harbors or aids terrorists.
